运动点目标序列图像检测性能分析

在点目标探测系统中,需要在虚警率容忍限度内,尽可能提高目标的探测概率。在单帧图像信噪比无法提升的情况下,常常采用多帧序列图像检测。然而,对于随机运动的点目标,采用多帧序列图像检测在什么样的情况下能提高探测概率目前还没有完整的结论。现从建立点目标及噪声模型出发,用理论估算和仿真实验的方法对这一问题做了分析,并得出结论。这些结论对目标探测系统的设计具有指导意义。

Performance Analysis of Detecting Moving Target by Image Sequence

To enhance the detecting probability under prescribed false alarming rate is an universal task in detecting and tracking system for point target. Detecting moving target through Image Sequence is naturally used in the cases that single image provides no room for further improving the detecting probability. However, till now there is no complete theory for whether detecting through Image Sequence contributes to improving the detecting probability. Evolving from the mathematic model of image noise and point target, this paper analyses the problem with theoretical estimation and experiment. A generic conclusion is put forward which may be helpful in design Target detecting and tracking system.
